Question

Quizplus · Accepted Answer

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation. This process occurs when an electron returns to its ground state from an excited state, releasing energy in the form of light.
